 It is possible to download and extract a prebuilt script with default settings.
 For example, to download the latest release you can run the following
 ```bash
-$ curl -fsSL https://github.com/fredrikekre/jlpkg/releases/download/v1.5.1/jlpkg-v1.5.1.tar.gz | \
-  tar -xzC /usr/local/bin

+    tar -xzC /usr/local/bin
 ```
 This will extract the executable script `jlpkg` and place it in `/usr/local/bin`.
 You can of course replace `/usr/local/bin` with any writable folder in your `PATH`.
 When using the prebuilt script it is assumed that `julia` is also in your `PATH`.
 
 The Bash completion file can also be downloaded from the repo. For example:
 ```bash
-$ curl -fsSL -o ~/.bash_completion.d/jlpkg-completion.bash \
-  https://raw.githubusercontent.com/fredrikekre/jlpkg/v1.5.1/src/jlpkg-completion.bash
+curl -fsSL -o ~/.bash_completion.d/jlpkg-completion.bash \
+    https://raw.githubusercontent.com/fredrikekre/jlpkg/v1.5.1/src/jlpkg-completion.bash
 ```
 Make sure to source this file in your shell startup file. For example, add the following to `~/.bashrc`:
 ```bash
